2020 –21 influenza season will coincide with the continued or recurrent circulation of Feb 23, 2021 Influenza is a highly infectious viral disease caused by influenza virus that can occur as a pandemic, epidemic, outbreak and in form of sporadic Flu: Caused by any of several different types and strains of influenza viruses. Different strains circulate each year.

Antigenic and genetic analysis of the hemagglutinin of ~13,000 human influenza A (H3N2) viruses from six continents during 2002–2007 revealed that there was continuous circulation in east and Southeast Asia (E-SE Asia) via a region-wide network of temporally overlapping epidemics Antigenic and genetic analysis of the hemagglutinin of approximately 13,000 human influenza A (H3N2) viruses from six continents during 2002-2007 revealed that there was continuous circulation in east and Southeast Asia (E-SE Asia) via a region-wide network of temporally overlapping epidemics and that epidemics in the temperate regions were seeded from this network each year. 2019-12-03 · Since the recent emergence of several subtypes of influenza viruses with pandemic potentials, there has been growing interest on the control of this infection worldwide. This study aimed to describe the 10 years of influenza activity in Cameroon between January 2009 and December 2018.

Influenza virus due to its wide host range and zoonotic potential poses such a significant threat to public health.

Influenza B virus causes acute febrile disease with respiratory symptoms similar to influenza A virus. Although influenza B virus used to be considered as less virulent and consequently less of a public health threat than influenza A virus (Glezen, 1982, Nolan et al., 1980), it has recently been shown that influenza B virus also has a significant global disease burden Here we show that the global circulation patterns of A/H1N1 (up to 2009), B/Victoria, and B/Yamagata viruses differ substantially from those of A/H3N2 viruses, on the basis of analyses of 9,604 haemagglutinin sequences of human seasonal influenza viruses from 2000 to 2012. Antigenic and genetic analysis of the hemagglutinin of ~13,000 human influenza A (H3N2) viruses from six continents during 2002-2007 revealed that there was continuous circulation in east and Southeast Asia (E-SE Asia) via a region-wide network of temporally overlapping epidemics and that epidemics in the temperate regions were seeded from this network each year.

The global anxiety and a significant threat to public health due to the current COVID-19 pandemic reiterate the need for active surveillance for the zoonotic virus diseases of pandemic potential. Influenza virus due to its wide host range and zoonotic potential poses such a significant threat to public health.

A/H3N2 genetic variants do not persist locally between epidemics but are re-seeded from East and Southeast Asia. The global circulation patterns of influenza A/H3N2 viruses are well characterized, but the patterns of A/H1N1 and B viruses have rem …. Global circulation patterns of seasonal influenza viruses vary with antigenic drift. Nature. 2019-12-20 Global circulation of influenza viruses Data source: FluNet, Global Influenza Surveillance Network (GISN) 0 1000 2000 3000 4000 5000 6000 7000 1 (85) 2 (85) 3 (85) 4 (83) 5 (79) 6 (79) 7 (79) 8 (79) 9 (77) 10 (78) 11 (78) 12 (77) 13 (77) 14 (77) 15 (75) 16 (74) 17 (74) 18 (73) 19 (72) 20 (73) 21 (73) 22 (73) 23 (72) 24 (71) 25 (72) 26 (73) 27 (70) 28 (71) 29 (71) 30 (72) 31 (72) 32 (70) Here we show that the global circulation patterns of A/H1N1 (up to 2009), B/Victoria, and B/Yamagata viruses differ substantially from those of A/H3N2 viruses, on the basis of analyses of 9,604 In 2020, after the global coronavirus pandemic began, influenza viruses mysteriously disappeared from global circulation (see WHO FluNet chart above). Some skeptics suspected that influenza was simply reclassified as covid, while many journalists and ‘fact checkers’ claimed influenza was suppressed by face masks and lockdowns. Understanding the spatiotemporal patterns of emergence and circulation of new human seasonal influenza virus variants is a key scientific and public health challenge.

2014), showing little regional persistence and a powerful source-sink dynamic in which viruses emerge from the East and Southeast Asian tropics and spread to the rest of the world, rapidly replacing endemic lineages. The Global Circulation of Seasonal Influenza A (H3N2) Viruses Antigenic Evolution. Antigenic cartography has shown that the antigenic evolution of A (H3N2) virus, since its Persistence Versus Seeding. Source of inter-epidemic strains.

Influenza virus circulation continues to be monitored to determine if the low activity levels persist after community mitigation measures are eased. Here we show that the global circulation patterns of A/H1N1 (up to 2009), B/Victoria, and B/Yamagata viruses differ substantially from those of A/H3N2 viruses, on the basis of analyses of 9,604 haemagglutinin sequences of human seasonal influenza viruses from 2000 to 2012. 2015-06-08 · Understanding the spatiotemporal patterns of emergence and circulation of new human seasonal influenza virus variants is a key scientific and public health challenge. The global circulation patterns of influenza A/H3N2 viruses are well characterized, but the patterns of A/H1N1 and B viruses have remained largely unexplored. 2008-09-12 · A recent phylogenetic study of ∼300 influenza A(H3N2) viruses in Hong Kong showed further evidence for global circulation and against persistence from season to season, with phylogenetic evidence that only 1 strain in 300 was related to the viruses circulating in the previous epidemic—a virus that might have been the result of low-level circulation, but which also could have been seeded Influenza A viruses are the only influenza viruses known to cause flu pandemics, i.e., global epidemics of flu disease. A pandemic can occur when a new and very different influenza A virus emerges that both infects people and has the ability to spread efficiently between people.
